Boiled and smoked catfish (Claria geriepinus) were evaluated in order to know omega-3 and omega-6 fatty acids potential of these processed fishes. Samples were analyzed for their fatty acids using modified AOAC methods and gas chromatography (gc). Findings shows that linoleic (Ω-6), alpha-linolenic (Ω-3) and gamma-linolenic were significantly higher in boiled catfish and covered respectively 9.0351e-7, 9.56501e-5 and 2.76276e-5 area when subjected to gas chromatography compared to the smoked cat fish. Also, both saturated and unsaturated fatty acids were present in appreciable amount in the processed samples. Therefore, catfish can serve as a potential source of essential fatty acids to human nutrition particularly in Nigeria where cat fish consumption is growing popular.

Microalgae are unicellular, photosynthethic organisms that can grow on diverse aquatic habitatss like ponds, lakes, rivers, oceans, waste water and humid soils. Recently, microalgae are gaining importance as renewable sources of biologically active food compounds such as polysaccharides, proteins, essential fatty acids, biopigments such as chlorophylls, carotenoids, astaxanthin, as well as vitamins and minerals.The bioactive food compounds of microalgae enable them to be part of multitude of applications in numerous industrial products for healthy life and ecosystem. This review article summarizes the applications of biologically active food compounds derived from microalgae as nutraceuticals, healthy dietary supplements, pharmaceuticals and cosmetics. Further, this review article highlights the importance of research focus on the identification and extraction of bioactive food compounds from the huge numbers of microlage that exist in nature for sustainable global food security and economy.

Docosahexaenoic acid (DHA) is one of essential fatty acids that are beneficial to health. Nowadays, the source of docosahexaenoic acid (DHA) is mainly obtained from fish which are extracted into fish oil products. However, the fish oil products still have some drawbacks in term of purity, acceptable flavor for costumers, and also their not environmental friendly production process. As an alternative solution, heterotrophic microalgae can be used as a potential source for DHA due to their excellence compared to fish oil products. The aim of this study is to isolate the heterotropic microalgae that can produce DHA. The heterotrophic microalgae were isolated from mangrove fallen leaves (Rhizophora apiculata) by using direct planting method. The morphology of pure microalgae colony were observed through light microscope and subsequently fermented for 14 days. Fatty acids were extracted and methylated through direct transesterification method. Identification and quantification of DHA were conducted by using gas chromatography. The results were four isolates of heterotropic microalgae, namely MTKC1, MTKC2, MTKC3, and MTKC4. The extract of MTKC2 that only showed the content of DHA with value of 9.2 % w/w. Therefore MTKC2 is a potential source for DHA. The MTKC2 was further identified by using molecular biology method and confirmed as Thraustochytrium aureum.

Throughout evolutionary history, elasmobranchs have developed diverse reproductive strategies. Little focused work, however, has addressed how neonatal nutritional state is affected by differing degrees of maternal investment associated with these markedly different reproductive strategies. To investigate the effect of maternal investment on the nutritional quality of pups during the early life history of an extremely viviparous elasmobranch, quantitative biomarker analysis including lipids, fatty acids and stable isotopes was conducted. Using the cownose ray Rhinoptera bonasus (histotrophic viviparous) as a model, we found that pups were initially born in a positive nutritional state, enriched in physiologically important essential fatty acids and nitrogen and carbon stable isotope values (δ15N and δ13C), a result of maternal intrauterine transfer. A systematic decrease in some fatty acids and δ15N values, as well as a decrease in cholesterol with growth, confirmed that these substrates were derived from maternal resources and used in initial metabolic processes following birth. An observed increase in condition factor, plasma essential fatty acids and triglyceride:cholesterol ratio with increasing body size identified a progression towards successful independent foraging with pups not displaying marked nutritional deficiency or fasting phases. Our multi-tracer approach allowed the identification of 2 size classes of young rays (<50 and <70 cm disc width) that displayed distinct physiological states. Since prenatal maternal investment is critical for offspring condition and to promote successful foraging post birth, understanding the trophic ecology and physiological state of pups during their first year is critical to guide management and conservation within nursery grounds.

Food is not just a pleasure in life, it is also an important factor for our health. Human nutrition is a mixture of nutrients, which are the only source of energy needed for survival. Energy-poor diet endangers many life functions, and above all the working ability. In the world, the meaning of the diet is very serious, and hence the demands for a –rational, healthy and safe diet are growing. Human nutrition contains saturated and unsaturated fatty acids. Essential fatty acids (EFAs) must be ingested in everyday diet because the body does not produce it. They are very important for human health. They are present in each cell of the human body and are an important factor for the normal growth, development and functioning of cells, muscles, nerves and organs. They are also used in the production of certain hormones - such as prostaglandins, which are crucial for the performance of certain important processes. The deficit from EFAs is due to a number of health problems, including more serious diseases.

Polyunsaturated fatty acids (PUFAs) comprise about 35-40% of the total lipid content from green algaeChlorella, reaching up to 24% linoleic acid and 27% α-linolenic acid inC. vulgaris. Also, microalgae nutrient composition may be modulated by changes in the culture medium, increasing fatty acid and microelement concentrations in the algae biomass. PUFAs, such as α-linolenic (n-3) and linoleic (n-6) acids, as well as its derivatives, are considered essential for dietary consumption, and their ability to regulate body chemistry has been recently explored in depth. A balanced fatty acid consumption is shown to counteract the negative effects of western diets, such as chronic inflammation and glucose intolerance. In this brief commentary, technological and practical uses ofC. vulgarisare explored as means to improve dietary quality and, ultimately, human health.
